Vehicle-spring



UNITED STATES PATENT OFFICE.

SILAS H. RAYMOND, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO THE ABBOTT BUGGY COMPANY, OF (HID AGO, ILLINOIS.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 394,393, dated December 11, 1888.

Application filed September 3, 1888. Serial No. 284,480. (No model.)

To all whom it may concern:

Be it known that I, SILAs H. RAYMOND, of Grand Rapids, Michigan, have invented certain new and useful Improvements in Vehicle- Springs, of which the following is a specification.

My invention relates to that class of vehiole-springs described in Letters Patent of the United States issued to myself and Franklin L. Raymond January 10, 1888, No. 370,161; and my invention consists of certain improvements in the class of springs shown and described in said patent, whereby the working of the spring is improved and the spring itself is concealed from view, thus adding to the attractiveness of the vehicle, all as hereinafter described and claimed.

In the accompanying drawings, Figure l is a bottom plan view of a vehicle-body having applied thereto my improved spring. Fig. 2 is a transverse sectional view through the body and the rock-shafts of the spring, the spring itself and its moving parts being shown in side elevation. Fig. 3 is a detail of the lower portion of the spring-bolt and particularly intended to show anti-friction rollers for the ends of the arms which actuate the springbolt.

In the drawings, A represents the vehiclebody, on the bottom of which are journalbearings, B, in which are journaled rockshafts C O, extending parallel to the sides of the body. Rigidly secured to said rock-shafts are spring-arms I) D, which project outwardly and support the body upon the gear. At the middle of said rock-shafts I secure rigidly two inwardly-extending arms, E E, whose lapping ends are movably secured between the bifurcated arms f f of a spring-bolt, F, by means of a bolt, G, passed through bolt-holes in the ends of the arms ff, said bolt having thereon anti-friction rollers or spools g g, upon which the free ends of the lapping bars E E play during the movement of the rock-shaft. The spring-bolt F extends upward vertically into a recess, H, formed in the bottom of the body A, the bottom of said recess providing a seat for a solid rubber block-spring, I, through which spring-bolt F is passed, and a nut, 2', turned upon the upper end of the v spring-bolt prevents its withdrawal.

entirely concealed within the recess H of the body-bottom, instead of projecting, as in said former patent, above the body-bottom into the space below the scat, where it is not only unsightly, but is more exposed to interference and injury. The anti-friction rollers g furnish an easy rolling bearing for the lapping ends of the arms E, preventing friction, and thereby obviating disagreeable noises and wear.

The construction hercinabove described provides an easy and efficient spring for vehicles, and a very light central spring may be used, because the leverage exerted thereon is quite longi. e., from the attaching-points of the spring-arms D to the vehicle-gear to the bearing-point of the lapping arms E, the rockshaft forming a movable fulcrum for said lever, and the strain is exerted in a downward pull and without shock.

I claim 1. In combination, the body A, rock-shafls O (7, journaled to said body and provided with supporting spring-arms D D and inwardlyextending and lapping arms E E, whose inner ends are movably supported upon antifriction rollers g g, carried by a spring-bolt, F, and a spring, H, seated within the body and to which the spring-bolt is connected, substantially as described.

2. In combination, the body A and rockshafts C C, j ournaled to said body and provided with supporting spring-arms :D l) and inwardly-extending and lapping arms E E, having anti-friction bearings upon the lower end of a spring-bolt, F, said bolt passed through a rubber block, as H, and secured thereto, substantially as described.

3. In combination, the body A and rockshafts O C, j ournaled to said body and provided with supporting spring-arms D D and inwardly-extending and lapping arms E E, having anti-friction bearings upon the lower end of a spring-bolt, F, said bolt passed through a rub ber block, as H, and secured thereto, and said block seated within a cavity in the body-bottom, whereby it is concealed from view, substantially as described.

SILAS H. RAYMOND.
